Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%
Ripple & Noise measurement bandwidth is 0-20MHz.
These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not
damage these modules; however they may not meet all specifications listed.
All DC/DC converters should be externally fused at the front end for protection.
Specifications subject to change without notice.
